Specification of Letters Patent.

Patented Nov. 20, 1906.

Original application filed October 20,1904, Serial No. 229,21'7. Divided and this application filed July '1, 1905. Serial No. 267,992.

To all whom, it may concern:

Be it known that I, LEwIs H. STONER, of Albany, county of Delaware, and State of Indiana, have invented a certain new and useful Cement Post; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This application is divided out of an application-filed by me October 20, 1904, Serial No. 229,247, for a cement post and process of making the same. I

The object of this invention is to make a post for fences or other purposes which is very cheap and quite strong and durable.

The striking feature of the post is its bellshaped base, which is molded into a bellshaped hole, so that the lateral portions of the lower part of the hole are undercut beneath the earth to receive the lateral extension of the base of the post.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a perspective of a line-post in place, the ground around the post being in vertical section. Fig. 2 is a perspective of a corner of braced post, the ground around the base of both the main post and brace being in vertical section.

The post consists of a base 10, that is substantially bell-shaped, the lower part being of considerably greater diameter than the upper part, so that the lower part of the base will project appreciably laterally under the soil that surrounds the upper part of the base. Said base also has on it protuberances 11, distributed irregularly over its surface, that project into the soil surrounding the post. The upper part 12 of the post is preferably integral with the base, and its sides are smooth down to a point a few inches below the surface of the earth in which the post is set.

The post is made preferably in the following manner: A hole is excavated in the earth that is substantially bell-shaped that is, the lower part of the'hole is laterally widened and out under the earth surrounding the upper part of the hole. Then concrete is introduced into the hole. This is done by partly filling the hole with thin grouting or cement and tamping into it boulders or stone until the hole is filled to within a few inches of the top. Then a mold for forming the top of the post is placed above said material in the hole for forming the base and concrete introduced into the top of the mold until the superstructure is formed. The superstructure has preferably smooth sides down to a point a few inches below the surface of the ground. When the concrete of the base hardens, it will be covered with innumerable small protuberances by reason of the semifluid concrete saturating the adjacent earth and running into its crevices in various directions, so that a very close union between the earth and the surrounding base is effected. This close union between the base and the earth, together with the fact that the lower part of the base extends into the undercut portion of the hole, and therefore below the earth surrounding the upper part of the base, will make a remarkably strong and durable setting for the post.

With the sides of the post smooth for a few inches below the surface of the earth the movement of the earth due to frost will not tend to move the post and loosen it to any extent in its setting. Likewise when such post is used for a line-post in a valley the upward pull of the line-wires of a fence cannot loosen or withdraw the post from the ground.

The corner-post shown in Fig. 2 has a brace 14 built in against it, with its brace 15 made in substantially the same way and in the same form as the base of the'main post.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A post having at its base a projecting part entering an undercut portion of the opening in the ground in which the post is located whereby any disturbance of the normal condition of the earth above said undercut portion incident to planting the post is obviated.

2. A post formed of plastic material molded in and extending above the ground, having at its base a projecting part entering an undercut portion of the opening in the ground into which the plastic material for the post is introduced, whereby any disturbance of the normal condition of the earth above said undercut portion incident to planting the post is obviated.

3. A post formed of plastic material, molded in and extending above the ground, the base being substantially bell-shaped and with the projecting part thereof entering an IIO undercut portion of the opening in the ground into which the plastic material for forming the post is introduced.

4:. A post molded in and extending above the ground having a plastic base provided with a projecting part entering the undercut portion of the opening in the ground into which the plastic material for forming the post is introduced, said base having protuberances extending therefrom into the surrounding undisturbed earth.

5. A post of plastic material molded in and extending above the ground having a base the surface of which has projections extending into and under the surrounding undisturbed earth, the upper part of the base and the post being smooth.

6. A post having its base portion projecting and entering an undercut portion of the opening in the ground into which the plastic material for forming the post is introduced, and a brace for said post with its base similarly formed, said brace being integrally connected with said post at its upper end.

7. A fence-post having a plastic base provided with a projecting part entering an undercut portion adjoining the opening into which the post is inserted, whereby any normal disturbance of the normal condition of the earth above said undercut portion incident to planting the post is obviated.

' In witness whereof I have hereunto a'Hixed my signature in the presence of the witnesses herein named.
